Sewage Backup in Your Basement: Health Risks and Why DIY Cleanup Is Dangerous
By Voda Tri-County Restoration · · 5 min read
Sewage contains bacteria, viruses, and parasites. Learn why category 3 water requires professional cleanup and how to keep your family safe until help arrives.
Sewage is 'Category 3' water
The IICRC classifies sewage as Category 3, or 'black water' — the most contaminated class. It can carry E. coli, salmonella, hepatitis A, and other pathogens that cause serious illness.
What to do right away
- Keep children and pets away from the affected area.
- Stop using sinks, toilets, and laundry until the line is cleared.
- Don't touch sewage-soaked items without gloves, boots, and eye protection.
- Turn off HVAC to avoid spreading contaminated air.
Why DIY isn't enough
Porous materials like carpet, pad, and drywall that contact sewage usually must be removed. Surfaces need antimicrobial treatment, and the area must be dried and verified. Professionals have the protective gear and equipment to do this safely.
Insurance coverage for sewage backup often depends on a specific endorsement on your policy, so check with your agent.
